Refrigerator Parts: What to Know and How to Replace Them

Got a fridge that’s making weird noises or not cooling right? Most of the time the issue is a single part that’s worn out, not the whole appliance. Knowing the key components and how to check them can save you a call‑out fee and get your food staying fresh again.

Common fridge parts that fail

Compressor – This is the heart of the cooling system. If it hums loudly or stops completely, the fridge won’t get cold. A faulty compressor usually needs a professional replacement because it involves refrigerant handling.

Thermostat or temperature sensor – When the fridge runs nonstop or never kicks on, the thermostat may be stuck. Most modern units use a sensor that can be swapped with a screwdriver.

Evaporator fan – The fan circulates cold air inside the freezer and fridge. If you hear a rattling sound or notice ice buildup, the fan blades might be dirty or the motor burned out.

Defrost timer and heater – These keep frost from building up on the coils. A timer that never triggers or a heater that’s not heating will cause ice to choke the system, leading to warm spots.

Door gaskets – Worn or cracked seals let warm air slip in, making the compressor work harder. You can test them with a dollar bill; if it slides out easily, the gasket needs replacing.

Step‑by‑step replacement tips

1. Unplug the fridge – Safety first. Pull the plug or turn off the breaker before you start pulling parts apart.

2. Identify the problem – Use the clues above. Listen for noises, feel for temperature differences, and check for ice buildup.

3. Get the right part – Look up the model number (usually on a sticker inside the fridge) and order a matching component from a reputable supplier.

4. Take photos – Snap pictures of wiring and screw positions before you disconnect anything. It makes re‑assembly much easier.

5. Replace the part – Most components like thermostats, fans, and gaskets are held with simple screws or clips. Remove the old piece, line up the new one, and tighten securely.

6. Re‑test – Plug the fridge back in and give it 30 minutes to start cooling. Listen for normal operation and check that the temperature drops to the right range (around 37‑40°F for the fridge, 0°F for the freezer).

If the fridge still isn’t working after you’ve swapped the obvious parts, it’s probably time to call a certified gas engineer. They have the tools to test the compressor, refrigerant pressure, and electrical safety.

Keeping a spare set of door gaskets and a basic fan kit on hand can cut down future downtime. Regularly clean the condenser coils (behind or beneath the fridge) with a vacuum brush to improve efficiency and prolong the life of the compressor.

In short, most fridge hiccups trace back to a few common parts. By learning how to spot a faulty thermostat, fan, or gasket, you can decide whether a quick DIY swap will do the trick or if a professional’s help is needed. A little knowledge goes a long way toward keeping your food fresh and your wallet happy.
